  • d. It is highly resistance to corrosion by liquid.
  • e. It must be malleable and ductile.
  • f. It must be flexible.
  • g.
  • h.


Which material is a better conductor of electricity Mcq?

Copper is the best known conductor of electricity.

What are the properties of conducting materials?

A conductor exhibits the following properties in equilibrium condition: A conductor always allows the movement of electrons and ions in them. The electric field of a conductor is zero allowing electrons to flow within them. The charge density of a conductor is zero.


Which has the highest conductivity Mcq?

Explanation: On a scale of 100, silver has 100 percent on high conductivity, copper has 97. When compared to silver and copper gold has only 76 percent.


Which is the best conductor Mcq?

Metals conduct electricity easily and the best conductor out of these are silver.


How does a motor generator work?

When an electrical current is applied to the motor, the magnets or windings create a magnetic field that both attracts and repels the rotor, causing it to spin. The spinning motion of the rotor drives the shaft that it is mounted on, which in turn can deliver the mechanical power wherever it is needed.


Does resistance change voltage or current?

Ohm's law states that the electrical current (I) flowing in an circuit is proportional to the voltage (V) and inversely proportional to the resistance (R). Therefore, if the voltage is increased, the current will increase provided the resistance of the circuit does not change.


What does 3kva mean?

A Volt is a measurement of electrical pressure and an Amp is a measurement of electrical current. The term apparent power is equal to the product of the Volts and Amps. Example: A 30 kVA 3 phase generator is capable of producing 10 kVA per phase or approximately 43 Amps per phase in a 415/240V system.


What do transition metals have in common?

The transition metals have the following physical properties in common: they are good conductors of heat and electricity. they can be hammered or bent into shape easily. they have high melting points (but mercury is a liquid at room temperature)


What is metal and non metal Class 6?

Metals are good conductors of heat and electricity. Non-metals are bad conductors of heat and electricity. Except for graphite which is a good conduction of electricity. Metals are lustrous and can be polished.


What is eddy current?

Eddy currents (also called Foucault's currents) are loops of electrical current induced within conductors by a changing magnetic field in the conductor according to Faraday's law of induction. Eddy currents flow in closed loops within conductors, in planes perpendicular to the magnetic field.


What are the 3 types of elements?

The elements can be classified as metals, nonmetals, or metalloids. Metals are good conductors of heat and electricity, and are malleable (they can be hammered into sheets) and ductile (they can be drawn into wire).


What is metal and non-metal Class 6?

Metals are good conductors of heat and electricity. Non-metals are bad conductors of heat and electricity. Except for graphite which is a good conduction of electricity. Metals are lustrous and can be polished.


What are metals for Class 6?

Metals: Materials which have certain properties like, lustre, malleability, ductility and are sonorous, good conductors of heat and electricity, are called metals.
